If you're going to get a thin filter, make sure you get a high quality one. Looks like the cheap ones may come into contact and scratch the center of the front element. Roger @LensRentals shows evidence of it. But only with the cheap, discount ones apparently, combined with the slightly protruding front element.

So, Roger @LensRentals has come up with some really useful information again. Cheap/discount thin filters can actually contact the front element of the 24-70v2 (and potentially others that have slightly protruding front elements) and scratch the center.

Yes, that works and it's what I use. But the point of the thread was is the thinner mount needed, and it isn't. The F-Pro MRC version works just fine, no additional vignetting, the lens cap fits more snugly (less of a gap, though there still is one at least with the side pinch cap that I have), and it costs 1/3 less.

Thanks all for sharing your vignetting reults! Just ordered the lens and B&W F Pro filter from B&H and saved myself an extra $300. What a nice surprise that was. Things like that do not happen to me. I almost ordered it last night but decided to post this question about filters vignetting.

It is indeed more or less the same as having transparent plastic on your sofa for protection. One could also think about condoms as another example. The additional protection ruins things, but some people would be in pain had they not used protection.

I used filters earlier, but noticed that without them outcomes were better. I still have the filters just in case I need them for something.... Haven't needed them yet and my front elements are doing just fine.

Ah yes, the age old question to use a filter or not to use a filter. For best IQ, no filter. For people (like myself) that aren't always careful or lucky, filters. I have taken filters off my lenses after 2-3 years and they're covered in scratches, so obviously it makes sense for me, but 99% of my shooting is outdoors in harsh conditions.

At your recommendation, I sold all my regular B+W filters to buy B+W XS-Pro versions, now you are promoting the regular B+W filters? not cool man! ... just kidding, actually my earlier (above) post was the last one for the day before I went to bed and didn't bother to check if everything I posted showed up. What I meant to say was that "I recommend XS-Pro version as it can be shared with 16-35 L II, where having a thinner version is better" .... but for some reason only the product name showed up in my earlier post.

I just hit “purchase” on the 24-70 II USM since I didn’t know when the sale would end at B&H. This is a great – but frustrating – thread for me because I thought I knew which filter I was going to purchase: Hoya UV Haze HD, but now after following this thread I am looking at the B+W XS Pro. I also have to admit that those suggesting no filter are making a pretty good case as well.

I do a lot of indoor shooting and plan to use this lens for video (mostly indoor). I’m no pro but really baby all the gear that I own so Dick’s Lens Hood protection method is intriguing.

At the risk of not getting too off-topic, can someone comment on the Hoya UV Haze HD versus the B+W XS Pro?
